'.PILING.

Specification of Letters Patent.

Patented sept. 19, 1911.

Application filed February 15, 1911. Serial No. 608,780.

To all whom it may concern:

Be it known that I, IVILLIAM NEILsoN, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inFiling, of which the following is a specification.

My invention consists of an improvement in metal piling, of the classwhe'rein a series of rolled metal piles are connected together at theiredges by means of co-acting hold ing portions, capable of relativelongitudinal movement and providing for lateral deflection of theseveral piles of a series when connected.

The particular object of the invention is to provide a constructionwhich may be rolled from a channel section to provide, along each edgeof the pile, a specially formed hook terminal adapted to intertit andco-act with a correspondingly formed terminal of an adjacent pile,whereby to provide at any position which the piles may assume withrelation to each other, a strong tight joint, capable of resisting thevarious strains, and whereby, at varying positions, different portionsof the interengaging terminals will be maintained in binding contact.

A further object is to so construct the terminals that the interengaginghold, one with the other, will be increased in propon tion to thestrain.

In various forms of rolled metal 4piling heretofore constructed anddesigned, employing flanged sections, there is more or less tendency toopen up the joint under strain, due to the spreading or wedging actionof the parts.

In my present invention, I form the pile in the fewest number of rollingoperations, from an original channel form, either of the commercialstandard proportions, or specially rolled as may be desired, utilizingthe metal and so distributing and shaping it, with relation to the mainbody portion or web of the section, as to best secure the objects inview.

In the drawings accompanying the speciiication: Figure l is a crosssectional View of a pile 'made in accordance with my invention,indicating the channel flanges from which the terminals of the pile areformed, in dotted lines. Fig. 2 is a similar View, enlarged, showing theedges of adjacent piles in interlocked position for a straight wallarrangement. Fig. 3 is a similar view,show

ing one of the piles deflected from the plane of the other. Fig. 4 is across sectional view of a specially rolled section as used in makingcorner or partition junctions. Fig. 5 is a partial view of a standardchannel section from which the pile is formed.

It will be understood that the several sections of piling, shown incross sectional view in the drawings, are of the desired length for usein the usual manner of using such devices, by driving one after theother, in interengaging relation, to form a continuous series.

Each pile consists of a longitudinal web portion 2 having boundary edgesarranged to telescopically inter-fit and co-act with the edges ofadjoining piles. In the blank from which the pile is formed, the channelflanges, indicated in dotted lines at 3, 8, are bent around to providethe main shank 4 of the hook terminal, the general tapering crosssectional dimensions of the channel 3 being maintained substantially outto the point de- `fined by the line b, b. Said line defines the slope ofthe inner face of the terminal hook 5 and extends transversely acrossthe central line a, a, of the web 2, at an angle of about 45.

The inner' terminal (5l of the hook 5 is tapered toward a rounded pointas shown, while the inner neck of the hook 5, at 7 is rounded to aboutthe same curvature to receive and form a good bearing for the coactingterminal 6 of the adj acont intertting pile, as in Fig. 2. The outershoulder of the hook 5 is substantially rectangular as at 8, having arounded corner terminal, the face 9 of the hook 5 being flat as shown,between said corner and the terminal G. The hook as thus formed issomewhat bulbous in cross section with the abruptly bent backwardlyturned interengaging terminal having the inner face 10 flat on the sameplane as the line l), b, as stated.

The receiving cavity 11 of the pile as thus formed is interiorly roundedas -indicated at 12, generally semicircular in form, adapted to receivethe hook terminal 5 with ample clearance, but whereby the walls of saidhook will, when inserted as shown, lie somewhat closely adjacent to theinner wall 12 of cavity 11, with an intervening space 13.

When two co-acting piles are interloeked in the manner shown, theirengaging faces tight joint, wedge-like in its nature, and wherebypulling strains on the piles tending to separate them, will serve towedge the contacting faces more closely together.

As illustrated in Fig. 3, one of the piles is capable of veryconsiderable deflection with relation to the other and, due to theformation of the hook terminal 5 and its rounded corners 6i, 8, and theexterior of the main shank 4, the parts will be maintained ininteritting engagement, making contact at the four different points c,(l, e, f, respectively. rIlhe same engagement will be made quiteindependent of which pile is defiected with relation to its companion.In either position of the piles, the space 18 may be utilized forholding a filler of any suitable material or substance, whereby to packthe joint.

In Fig. 4, I show a specially jointed section, consisting of the centrallongitudinal body portion 14 having extending from it at suitablepositions, a plurality as 2, 3 or 4 hook members, depending upon thedesired number of joints to be made. These hook members are of the sameshape, proportions and arrangement as the hook members 4 of the pilesections just described, and are identified with corresponding numerals,primed.

The manner of using said jointed section will be readily understoodwithout further illustration or description, beyond the mere statementthat the hook terminals of the pile sections are telescopically engagedwith the hook members of the joint section according to the direction ofthe wall to be built, the holding effect and coperation being the sameas described as to the pile sections.

The joint section may be made as shown in the drawing and all or certainones of its hook members utilized as desired, or the joint section maybe made with the particular number of hook members required for the workin view, and arranged around the central core 14, at the positionssuitable for the direct-ion of the piling wall to be connectedtherewith.

The particular advantages of the invention reside, as to the pilemember, in its facility of manufacture from a channeh form; theadvantages arising from .the coacting single hook members without t-henecessity of supplemental bracing portions, and the facility forerecting piling structures in any desired direction laterally, due tothe construction of the pile sections themselves and of the connectingjunction member, when required.

It will be understood that the pile may of course, be rolled indifferent weights and proportions as to cross section and may beotherwise changed or varied by the manufacturer in specific features ofdetail, Within the scope of the following claims:

lli/lhat I claim is f l. A rolled metal pile comprising a web portionand an integral laterally curved connecting portion extending beyond theplane of the web, rounded backwardly thereinto and terminating in a hookterminal having a flat inner face coinciding with a plane extendingdiagonally across the plane of the web of the pile.

2. A rolled metal pile comprising a web portion and endmost integrallaterally curved connecting portions extending beyond the plane of theweb, rounded backwardly thereinto and terminating in hook terminalshaving flat inner faces coinciding with planes extending diagonallyacross the plane of the web of the pile.

3. A rolled met-al pile formed from a channel section, each flangeterminating iu a hook at one end having a flat inner face correspondingwith a plane extending diagonally across the central plane of the web ofthe pile, and an interiorly rounded recess and an exteriorly shoulderedterminal, substantially as set forth.

4. A rolled metal pile comprising a web portion having a. semi-circularportion at each end thereof and on one side only of the center line ofthe web, said portion being formed at each edge into a hook having areversed terminal provided with a flat bearing face, the plane of whichextends diagonally across the central plane of the web.

5. A rolled met-alpile comprising a web portion having a flange at eachend thereof and on one side only of the center line of the web, saidflange being formed at each edge into a hook having a reversed terminalprovided with a bearing face, the plane of which extends diagonallyacross the central plane of the web, said bearing face being continuedinteriorly and exteriorly whereby to define a receiving cavity for thehook of a co-act-ing pile and a rounded outer surface corresponding tothe surface of the original flanged section respectively and merginginto the web of the pile, substantially as set fort-h.

6. A rolled meta-l pile member consist-ing of a main body portionhavinga plurality of integral rounded hook members terminating in inwardlyturned ends having inner [iat sloping faces extending diagonally acrossplanes which bisect the main body portion of the pile member.

In testimony whereof I hereunto a-flix my signature in the presence oftwo witnesses.
